To have access to this zone, at least one person in the raid must have completed the quest line that starts with Daecon Joh'n on the airship docks in Paineel. The final quest, The Captain's Crystal, requires killing the last boss of The Vigilant: Rescue. Each member must be level 90 to enter, but only one person on the raid (the one clicking the raid party in to the zone) is required to completed the access quest.
